David Lewis – Assistant Professor (CV)
I am interested in understanding controls on the movement of nutrients and energy in ecosystems, human-environment interactions, and their implications for ecosystem structure and function. My research presently focuses on freshwater wetlands and intertidal habitats in mixed-use landscapes. I collaborate with natural and social scientists and environmental managers to better understanding biophysical and human controls on ecological processes. My teaching program includes graduate and undergraduate courses on various areas of ecology and environmental science.

Sharon Feit – M.S. 2012
Masters thesis: “Variability in hydrology and ecosystem properties and their role in regulating soil organic matter stability in wetlands of west-central Florida.” Sharon now works for Barr, an engineering and environmental consulting firm in Minnesota, where she works on endangered species, habitat assessments, wetland/waterbody surveys, and, regulatory permitting.
Lab Manager and Research Technician, 2011-13
Kristine spearheaded a project using the rare stable isotope of nitrogen (15N) to investigate rapid storage of N into stable organic forms in coastal wetland soils, focusing on salt marsh and mangrove forest habitats. She also managed our lab, from coordinating schedules and budgets to maintaining highly specialized instrumentation. Finally, while here at USF, she participated in outreach by using soils to explore sustainability themes with Native American students at the College of Menominee Nation, in Wisconsin. Kristine is currently a technician and manager in the Univ. of Cincinnati Stable Isotope Biogeochemistry facility.
Jewel Brown – B.S. 2012, Honors
Undergraduate honors thesis: Interactive effects of simulated sea-level rise and warming on microbial carbon and nitrogen cycling in mangrove and salt marsh soils. Selected for presentation at the USF Undergraduate Research and Arts Colloquium. Jewel is now in medical school at the Univ. of South Florida.
